United States Patent BARBER SHEARS George J. Chuba, Dim, Mich.

Application May 16, 1955, Serial No. 508,530

2 Claims. (Cl. 250-271) This invention relates to new and useful improvements in scissors and more particularly to an improved form of barbers shears.

An important object of the present invention is toprovide a barber shears having an adjustable thumb loop which permits the shears to be adapted readily to the hand of the user.

Another object of the invention is to provide barber shears of the above-mentioned character that are easier and less tiring to use.

Still another object of the invention is to provide a barber shears of the above-mentioned character wherein proper adjustment of the thumb loop enhances the cutting action of the blades and generally improves the operation of the shears.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the drawing forming a part of this specification and wherein like numerals are employed to designate like parts throughout the same:

Fig. 1 is a plan elevational view of a barber shears embodying the invention;

Fig. 2 is an enlarged, fragmentary, transverse sectional view taken on the line 22 of Fig. 1;

Fig. 3 is an enlarged, transverse sectional view taken on the line 3-3 of Fig. 1; and

Fig. 4 is an enlarged, fragmentary, longitudinal sectional view taken on the line 4-4 of Fig. 1.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numerals and 12 designate the cutting blades of the shears. The blades are of conventional size and shape and are pivotally interconnected at 14. The shank portions 16 and 18 of the blades 10 and 12 extend rearwardly in divergent relation in the usual manner, and the shank 18 is provided with a conventional, integrally attached finger ring 20. The shank 16 on the other hand is provided with a removable and longitudinally adjustable member 22 having a thumb ring 24 formed thereon. In usethe thumb is inserted in the ring 34 and the third finger in the ring 20. The little finger rests on the usual extension 26 formed on the ring 20.

A novel feature of the invention is the provision of the adjustable member 22. The usual practice is to provide a thumb ring 24 integrally on the shank 16 and in fixed predetermined relation with respect to the finger ring 20. This construction has the disadvantage that the rings 20 and 24 may not and usually do not fit the hand of the user. the rings 20 and 24, and an arrangement that adapts the rings for the hand of one person may not work at all for the hand of another person. If the rings 20 and 24 do not properly fit the hand, the shears simply do not operate satisfactorily, and the users hand quickly be comes tired. If the thumb ring 24 is too far back for the natural position of the thumb, it is difiicult, if not impossible, for the user to grip the ring so as to press the cutting blades 10 and 12 properly together. Also,

There is no universal position or arrangement of improper positioning of the thumb ring 24 causes the blades to move or jiggle in use, and this makes it difficult to use the shears properly with a comb, as in shingling.

According to the present invention, the thumb ring 24 is made an integral part of the member 22 and the latter is longitudinally adjustable on the shank 16. To this end, the member 22 is provided with a longitudinal bore 28 which receives the shank l6, and the latter is longitudinally slotted, as at 30. A screw 32 carried by the member 22 extends through the slot 39, as shown in Fig. 4, and a nut 34 on the screw co-operates therewith in I holding the member 22 in a selected, longitudinally adjusted position on the shank 16. When the nut 34 is loosened, the member 22 can be easily adjusted on the shank 16; and when the nut 34 is tightened, it holds the member 22 securely in a selected, adjusted position.

The longitudinal extension 36 at the inner side of the member 22 has an edge strip 38 of rubber or the like fastened thereon for engagement by the finger ring 20. The finger ring 20 engages the strip 38 as the blades 10 and 12 move to the fully closed position. Thus, the strip 28 serves as a bumper and softens the action of the shears. Both'the flange 36 and the rubber strip 33 are sutlieiently long to engage the ring 20 in all adjusted positions of the member 22.

The adjustable member 22 permits the thumb ring 24 to be adjusted relative to the finger ring 20 and to be positioned properly in accordance with the users hand. The thumb ring 24 should be positioned to receive the thumb comfortably when the third finger is inserted in the finger ring 211. If the two rings 2% and 24 are properly positioned to fit the hand, the thumb, by its natural motion, will force the two cutting blades 1%) and 12 onto the comb, thus assuring a better and more positive cutting action. Also, properly positioning of the rings and 24 enables the user to hold the blades 10 and 12 essentially stationary on the comb to provide a better and faster cutting action.

The latter result is achieved primarily by an improved balance of the shears. Also, the shorter stroke thus pro vided results in a faster motion and greater cutting power. If the thumb ring 24 is properly positioned relative to the finger ring, the users hand is relaxed and comfortable, and stretching and straining of the thumb is prevented. The rubber bumper 36, 38 reduces noise of operation and achieves an essentially smooth performance.

Having thus described the invention, 1 claim:

1. A scissors comprising a pair of pivoted blades having rearwardly extending, divergent shank portions, a finger loop on one of said shank portions, a thumb loop on the other of said shank portions, said thumb loop being a separate entity and longitudinally adjustable on the shank with which it is associated, and a longitudinal resilient bumper on said thumb loop extending in the direction of said finger loop and engageable therewith in all adjustable positions of said thumb loop.

2. A scissors comprising a pair of pivoted blades having rearwardly extending, divergent shank portions, one of said shank portions formed with a finger loop and the other of said shank portions having a longitudinal slot therein, a member defining a thumb loop longitudinally slidably mounted on said slotted shank, and fastening screw means carried by said member extending through said slot adjustable to hold said member in a selected,'

longitudinally adjusted position on said shank.
